Certain current complications following ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction (within the 28 day period) (I23)

ICD-10 code I23 covers various complications occurring within 28 days after a heart attack, specifically ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarctions. These codes identify issues like heart wall rupture, blood clots, and valve damage that arise soon after the initial heart injury.

The codes in the I23 category are used to classify specific problems such as hemopericardium (I23.0), which means blood in the sac around the heart following a heart attack. Other examples include atrial septal defect (I23.1) and ventricular septal defect (I23.2), both referring to abnormal openings in the heart walls caused by infarction. Rupture of the cardiac wall (I23.3), rupture of chordae tendineae (I23.4), and papillary muscle rupture (I23.5) are critical mechanical failures leading to impaired heart function. The presence of thrombosis in the heart chambers (I23.6) indicates clot formation after the infarction. Post-infarction angina (I23.7), or chest pain after the attack, and other related complications such as mitral valve regurgitation and arrhythmias (I23.8) are also included. Using the ICD-10 code for post-myocardial infarction complications helps in accurate diagnosis, treatment planning, and reporting for these severe heart attack aftermaths.
